Walter is a mechanical engineer at National Geographic. Thirty-two years ago, he answered an anonymous advertisement in the Washington Post for an engineer. Unsure of exactly what he was interviewing for, Walter brought along a crossbow trigger he had built to give an example of his capabilities and was offered the job on the spot.
His task is to make the gear that can’t be bought. Photographers come to Walter with a technical problem or need, and he builds the solution — from underwater camera housings to remote-control cars to a life-size hippopotamus. Anything a photographer needs to get the shot, Walter finds a way to make it.
